Important note about community–contributed projects
The IRIS DMC has moved many community–contributed software projects and legacy applications to Seiscode, our community repository for software used in seismological and related fields.
IRIS distributes seismology software for data requests, visualization and analysis. Click the package button to navigate to the download page (or request form if applicable). Alternative views are available by clicking in the 'View' dropdown list or click the 'View software archive' button to view the complete software archive. You can sign up to receive announcements about IRIS DMC software at the software-info topic in the IRIS Message Center.
PQLX (PASSCAL Quick Look eXtended) is open-source software for evaluating seismic station performance and data quality.
This current P4 release is a patch release to address a potential compilation issue in the previous 2011.365.P1 release. More details can be found in the Revision History tab.
The Matlab library IRISFETCH allows seamless access to data stored within the IRIS-DMC as well as other data centers that implement FDSN web services. Routines are provided to access event (earthquake) information, station metadata, and time series data. All retrieved data is converted into structs for use in MATLAB scripts.More...

1 – If more than one version is listed it means that a specific set of functionality was added or removed and legacy versions that preserve behaviors are archived.
2 – Development group(s) responsible. If IRIS and another group is listed, this usually means IRIS funded an external group for development.
PASSCAL provides open-source software for downloading seismic data from REF TEK RT72A, RT130 and RT125, and Quanterra Q330 recorders, for quality assessment, and for conversion to other data formats for analysis and archiving at the IRIS Data Management Center. More information
